IMPROVEMENT IN .SAW-FILING' MACHINE.

The Schedule referred to in these Letters Patent and making part of the sume.

To all whom it may concern Be it known that I, HENRY OBELL, of Emporia, in the county of Lyon, and State of Kansas, have invented a new and useful Improvement in Saw-Filing described. A

Figure' 1 represents a front elevation of my improved machine;

. Figure 2 represents a plan view ofthe same; and

Figure 3 representsa detail View. Similar letters of referenceindicate corresponding parts.

A represents a {ile-holding rod, provided with the arms B at each end, for holding the handles C of the file.

One of the said arms is rigidly fixed to the rod, and the other arranged to be detached for the insertion of the tile-handles when containing the file, the ends of which are inserted in sockets in the inner ends of the handles.

The other ends of the handles are fitted into holes in the arms, in a manner to allow the file to be turned on its axis to t the angle of the teethof the saws.

The rod A is supported in the armsD of a holdingbracket, E, pivoted to a clamp, F, having a slot, G, for the reception of a portion of the plate of a saw, and securing it to the. saw by the Aset-screw H.

'lhe saidl rod A is so supported by the said arms, that it has freedom to reciprocate therein, `to admit of the to-and-f'ro movement of the le 'past the tooth, whereby the filing is accomplished, and the bracket E is arranged to swing on its pivot E', to allow the file to be adjusted to the line of the face ofthe teeth, i

whether at-right angles to the saw-plate or any other angle, and a set-screw, I, passing through a curved slot in the bracket, and screwing into the clamp'F, is provided for holding the bracket in the desired position.

The apparatus is to be moved from one tooth to another, and properly adjusted for each, in the process of ling, the operation of which will be fully iinderstood without further description.

Having thus described my invention,

I claim as new, and desire to secure by.Letters Patent- The construction and arrangement of the slotted angular clamp F, the slotted angular plate E, adjustable upon the clamp F, and the slotted gnideD, adjustable upon the plate E, as herein shown and described.

The above specification of my invention signed by me, this 20th day of June, 1868.
